If I remember well, I read something about system clock
being too fast on SMP computers.
It's happening on my system since I installed kernel 2.4.10
SuSE (about 2mn a day). Can it be cured ?, beside loading
twice a day from a time server...

Sorry, unless your machine is SMP, this is totally unrelated to the problem
discussed in this thread. Have you tried replacing your BIOS battery?

As mentionned in the original message maybe not clearly
enough, the machine indeed is SMP : 2xPII 266Mhz
I finally found a working solution by reading hwclock's man
: I added the following script to /etc/cron.daily, named
bbb_local_time :

#!/bin/sh

#
# paranoia settings
#
umask 022

PATH=/sbin:/bin:/usr/sbin:/usr/bin
export PATH

hwclock --adjust	# correct HW clock
hwclock --hctosys	# set SYS time from HW

This seems to keep the time correct +/-2 seconds during
working time (8-23).
I might add a correction from a time server by midnight
should the drift be more important. Still testing as it has
been operating only three days..
